Detection Algorithm for PSS Codes

This article discusses the detection algorithm for PSS (Primary Synchronization Signal) codes. We provide a detailed explanation of the PSS detection algorithm specifically designed for TDD-LTE systems and implement a comprehensive MATLAB simulation to better understand its performance characteristics. The simulation employs cross-correlation techniques between received signals and locally generated PSS sequences to achieve synchronization. During the simulation process, we consider various realistic scenarios including channel fading, multi-path effects, and additive white Gaussian noise (AWGN) to simulate practical application conditions. The algorithm implementation involves key MATLAB functions such as xcorr() for correlation computation and awgn() for channel noise modeling. Furthermore, we explore optimization strategies including threshold-based peak detection and sliding window approaches to enhance the algorithm's efficiency and detection accuracy. Through parameter tuning and performance evaluation using metrics like detection probability and false alarm rate, we aim to contribute to academic research in the field of PSS code detection algorithms.
